I installed an 800 watt xplod amp and one 12 inch woofer, i still have the stock radio and stock speakers, the stock woofer and amp were disconnected and i ran the lines to the new amp. It seems that the amp is taking all the juice out of my battery and it kills it. what can i do.. is a capacitor good for just one amp and one sub?

 

its not a capicitor you need... from what i can understand it sounds like you have your amp hooked up to a constant power source thats eating up your battery power when the cars turned off.

 

when i shut off my car the light on the amp goes out. Someone told me to try hooking up the amp somewhere in the fuse box. do you think that might help?

 

i have mine hooked up to the cig lighter and it works fine. you might want to give that a try

 

Dont hook the amp Power to teh fuse box. Try changing the remote turn on. But if you say that the amp goes off when you shut the car off i think something else is causing it. It sounds like the amp or something is still drawing power when off

 

do you guys think it might be the amp, hyper white foglights and everything else normally on when driving at night? maybe all that draws too much power.. everything is stock exept for the sub, amp, foglights and LEDs on the door and dome lights?

 

When does it kill it? Over night or if the car is off and your running the stereo? How old is your battery?

 

Great question. How old is your battery?

 

its about 2 years old, when the car runs the voltage is 13 volts or higher when i shut if off take the key out and leave the lights on, they shut off after like 10 seconds, when i try to start it the starter is really slow and barely starts the car. im in Iraq right now, i should be home in 2 months, i will get my car a new battery n tune up when i get back. i miss my baby

 

Sounds like the battery is your problem

 

how long does the battery usually last?

 

All depends on what kind of use and abuse. IF the battery is let to go dead a few times it will kill it faster.

 

i will change my battery when i get back home, i appreciate the help, thanks!

 

I would try one other thing before you replace the batter.

(1) Disconnect the power source from the amp (actually remove the power cord from the amp), and start the car that way.
(I would also remove any other cables that are connected to the amp, but that's just my style of work.)

Removing the power cord from the amp guarantees that the amp is not in play what-so-ever when you are starting the car.

[I]Try having your batter recharged to its full capacity (You might be able to do that for free at most major auto part retailers; 'Pep Boys, Auto Zone...')[/I}

(2) If that works, than try starting the car with the amps power connected again.

If the problem reappears you know the problem is the battery feeding more power to the amp then it could spare.

PS: I hope your problem is that simple.

 

thats a good idea, i didnt think of doing that. thanks for the help!
